# Whole numbers in expanded form review

Review writing whole numbers in expanded form, and try some practice problems.

## Expanded form

Expanded form is a way to write a number by adding the value of its digits.
We can use a place value chart to think of the value of a number's digits.

### Example

Let's write $7229$ in expanded form.
ThousandsHundredsTensOnes
$7$$2$$2$$9$
$\phantom{7229}=7000+200+20+9$
$7229$ in expanded form is $7000+200+20+9$.

## Practice

• Which one of you is named N10
• its me hi, i'm the proplem its me
• Hi? how do you live life to it's limit
• make life into a variable then apply the limit to infinity

lim x => inf life(x)

Though, I believe its undetermined
• what is 5643826 x 67363737865
• I got 380189215219671490.

I used a variation of the Vedic multiplication technique of vertical and crosswise. You might want to look up this method for multiplying numbers with several digits.

Have a blessed, wonderful day!
